For obtaining the:abovea.mentioned results I provide means, mounted rigidly with-respect; to the pick-up roll, for constantly engaging the fountainfrollyin spite 'ofizany vibration thereof,

' and guiding a uniform film of ink to the pick-up roll. So as to be rigidly mounted with respect to the pick-up roll, I locate a pair of suitable brackets on the bearings 18 of the pick-up 4 roll. In these brackets are a pair of eccentric bushings 19 which can be turned to adjust their centers toward or from the pick-up roll to control the thickness of the ink film left on the pickfrom the pick-up roll 11 and it has only a small afacorporationofVirginia1 I I t e; m er-F5,iezsggseriaruo.'ei'mniif ltcnewed May-24,1934 j j,"

1'1 and its surface 24, about a quarterway around itsjournals, is concentricwiththe bearings. As the edge turnstoward or, from the pick-up roll, the rear part of it along the surface 24 will not change its] distance from that roll. This distance is adjusted as stated above by turning the Qqoentric bushings and after adjustment it remains constant. The. thickness or .inkisdetermined by the blade 15, and the knife 23 merely removes all of it from the roller "10 and "permits 5 it to,be drawn away bythe pick-up rollfll.

The pick-up roll 11;can be rotated in either direction andthe two rolls can be rotated in opposite directions or the same direction, as desired, with this mechanism because the is not transferred directly from, one to the other; I j A t In the old construction the pickup roll'islr ig id IYm unted but the fountain roll is pivotally mounted for adjustment and is also spring-supported. This mountingis some times detrimental to the close adjustmentrequired between the we ro rs theeld; arr n emen v b ti inci ent to themec ne an t e variability e j th 1e l.-9 th k;i 1 .;.the quntain 1 ha somewhat affected the space between the rollers and this has prevented the keeping of the two rollers, at every instant, at the same distance from each other. 7

With this deflector knife, the knife edge being held 1 against the fountain roll, preferably, it scrapes the surface of the fountain roll and feeds the ink into contact with the pick-up roll through the concave space above theknife. After adjustment this space is constant and cannot be affected by any change in the position of the fountain roll, which may be moved up and down a short distance without affecting the delivery of the ink or the thickness of the film which it transfers to the pick-up roll.

It is to be noted that the deflector knife is mounted on bearings rigidly mounted with respect to the pick-up roll so that, if that is permitted to move, the deflector blade will have to move with it. Thus no vibration of either roll will affect the continuity of the ink film or its uniform- Although' I' have illustrated and described only one form of the invention I am aware'of the fact that modifications can be made therein by any: person skilled in the art without departing from A the scope of the invention as expressed in th'e' claims.
